WHEEL FOR MOTOR AND OTHER VEHICLES.

Patented Apr. 1,1913.

Application filed February 20, 1909. Serial-No. 479,207.

T all whom it may concern:

Be it known that I, ROBERT XVILLIAM SEWELL, of Brooklyn, New York, United States of America, have invented new and useful Improvements in and Connected with lVheels for Motor and other Vehicles, of which the following'is a specification.

This invention relates to an improvement in cushion tires for wheels constructed with outer and inner fellies and in which any shock or vibration imparted to the outer felly will be taken up by a cushioning elei ment and not transmitted to the hub of the wheel and thence to the vehicle to which the F wheel is attached.

One object of the invention is to construct and adapt the cushioning so that radially as well as laterally imposed shocks will be taken up partly by eompressionand partly by tension on the cushioning element.

Another object of the present invention is to provide means for preventing undue lateral displacement of the cushioning device, while at the same time permitting limited lateral movement thereof suificientto relieve shocks in that direction.

A further object is to so construct the cushioning element, that any compression thereof may be taken up in the center in stead of causing the sides of said element to be unduly spread.

Further objects and advantages will ap-,

pear from the following description with reference to .the accompanying drawings,- wherein,

Figure 1 is a side view showing the rel- .ative positions of the inner and outer fellies when thewheel is conveying a load; Fig. 2 is a radial section through a part of Fig. 1 on an enlarged scale; and Fig. 3 is the same as Fig. 2 embodying a modified form of the clamping rings.

Referring now more specifically to the drawing designates a wheel comprising the outer and inner rims or follies A and A which are conccntrically arranged. The inner folly or rim A. which is secured to the 7 wheel spokes is preferably provided with a suitable steel tire A. Between these two follies or rims and resting upon the tire A" (when en'iployed) a cushioning element B is secured, (see Figs. Q'and 3) consisting of any suitable shock absorbing material. In this illustrative embodiment, the cushion element Bis formed substantially H-shaped.

thecentral portion thereof fitting between the tWo rims A and A while the flanged edges fit against the faces of the rims, preferably in cut-away portionsof the rim, and are secured thereto by means of bolts or screws, G and G (see Fig. 3) the heads of which are counter sunk in the annular rings E and F which preferably lie flush with the lateral edges of the rims. But the particular formation of the cushion element may be varied atwill so long as it embodies an intermediate compression member and relatively thin annular-portions on either side of and integral with said compression mem ber, attached to the fcllies radially within and beyond the intermediate compression member.

In Fig. 3 there is shown a modified form of the inner ringsF The outer rings E in this figure are of substantially the same construction as in Figs. 1 and 2, but the inner rings are bent laterally as at F and extended radially so as to overlap the rings E, thus forming an inclosure or guard for the cushion element and at the same time permitting freedom of relative movement of the fellies or rims radially while limiting their relative displacement laterally, though not suiiiciently to destroy the absorption of lateral shocks.

From the foregoing description it will be understood that when the Wheel is. under pressure, the cushion element will be compressed adjacent to the point of contact with the road bed. The inner and outer follies however, being capable of relative radial movement, and also of limited relative lateral movement. the shocks or vibrations will be transmitted to the cushioning element outer felilies said thin annular portions being connected with the fellies radially Within and beyond the intermediate compression member, respectivelv; said thin annular members be ing inte ral with said intemnediate compression member ofsziid spacingmeans.

EL vehicle Wheel eompllsing inner and and" an intermec liate resilient spacing means connecting said fellies and yieldingly lr l=:.i1]g relative movement be tween them by the elasticity of said spacing means in the directions of: both tension and compression; said spacing means comprising an intermediate compression member and relatively thin annular portions 011 either side oi. saicl compression member; said thin annular gaortions being connected with the fellies moially Within and beyond the intetznedliate compression member, respectively; said thin annular members being integml with said intermediate compression member of said spacing means and together constituting therewith a rubber annulusof substantially H-shaped cross section.

In testimony whereof 1' ME my signaturein. presence of two Witnesses.
